Loosen the CPA valve terminal from the mounting surface (see section "Dismantling the CPA valve ter- minal" in this chapter). 2. Unclamp the CPA valve terminal. To do this loosen the fastening screws of all the components in the valve locations by two turns.
- Page 96 5. Maintenance and conversion Fitting 1. If you wish to add valve locations, fit the appropriate manifold block (EV1 or EV2) onto the sub-base. Then fit all the valve locations and the end plate (see section "Replacing valve, reserve and addi- tional pressure supply plates"...
